That yoshi sounds good.i have the lv10 on my mt10,but I like hearing different muffler sounds

Never touch a lambda sensor with your fingers. It's trash afterwards.

Here is a tip for removing cats on 2022+ MT-10 Along with the mounting screws ALSO remove the two little machined aluminum blicks that the mounts use ...THOSE little Bstards like pinch the cat tightly in place which wont allow the cat to twist in the slightest which can make nigh seemingly imossible to pound off! Ask me how I know lol

I guess you didn't read the instructions? You don't install an exhaust clamp in front of the muffler, it's only a slip fit with a spring.
